Hi all, I noticed that the rear arms of the drone shakes a lot, is this normal or should I contact assistance?
Here a small video

Thank you

No idea if it's a common issue or not but from an engineering standpoint that is only going to get worse over time. I'd contact support and see what they say.

More likely, the prop is out of balance. Try replacing all props or at least the rear with the extras your kit came with.

Sorry, I forgot to mention it, but of course I tested with different propellers. I bought the fly more combo and I tested every propellers available that are 4 for each type. Same results. The problem looks more like a flex or an excessive tolerance in the articulation of the arm
Edit: after further investigation, I confirm the arm can move a cuople of millimeters (measured at the the top end of the arm).
Here the video
Has anyone else noticed this problem?

had the same. i just replaced the propeller and it went away. the one that came attached was probably out of shape.

Mine flys stable too, but from a mechanical point of view, this issue could cause problems in future. What I'm trying to understand if it's working as intended or not, and if someone else noticed the same behavior.
The assistance looks offline right now in my country, I'll try to contact them Monday next week.

THat looks out of balance.

Yes, looks like that. As mentioned I tested with different propellers, but I get always the same results. If you look the first video, the front arms doesn’t shake. So I ussume that propellers are balanced, but if I switch the front propellers with the back propellers, the back arms keep shaking. Tomorrow I’ll test if the motor rotation without propellers cause shaking too, maybe is something wrong with the motors

Hope you get it sorted out.

I would get the drone replaced, not worth paying that much for the drone and having issues.

Doesn’t look right contact dji support.com

This is probably a motor out of balance or shaft bend. I will contact support and get it replaced ASAP.

Thank you all for your advices, I’ll do it.

I do not see the same vibrations in the rear arms of mine. But I do see the same amount of "play" in them as you do. If replacing props does not fix it, then I would start a repair case.

I am having the same issue: https://forum.dji.com/forum.php?mod=viewthread&tid=253460

NO. it's happening again. with the new props i'm still getting the shake in the rear legs.

I suspect that the bushing mounts in the arm joints were not installed correctly. Return it.

Having the same was quite bad at one point also if you look on the rear arms it’s rubbing against the body of the drone effectively weakening the plastic of the arm not sure if it’s the cause or it’s a cause from the shaking
